SELF-LOCKING WINDOW-OPERATING DEVICE.

Application led March 8, 1915.

To fait /wwm t may concern.'

Be it known that l, STEPHEN E. CIBULAS, citizen of the United States, residing at Bridgeport, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Self-Locl ing WVindow-Operating Devices; and I do hereby declare the following tobe a full,`

clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to window operating devices, and particularly to a self-locking feature for same.

Referring to the dra-wings wherein- Figure 1 represents a broken vertical inside elevation of a window frame closed, and its supports, and broken view of the operating rod; Fig. 2 is a broken sectional view on line 2-2 of Fig. 1; Fig. 3 shows the window open, and an upper plan view of the window sill, broken View of the operating rod, broken sectional view of the glass and their supporting uprights; and Fig. 4 shows the position of the device and window when open, broken sectional view of the window and window sill, and sectional view of the operating rod on line 4-4 of Fig. 1.

The window frame comprises the top rail 1, bottom rail 2, side rails 3 and 4, and the glass supporting T-shaped rails 5, support-v ing the several sections of glass 6, and is susw pended from the bar 7 by the hinges 8. ThisV bar is secured to the angle iron and uprights A and B.

9 is the operating rod having a reciprocating longitudinal movement in front of the window by any well known hand operating means (not shown). This rod is supported at proper intervals by anti-rictional boxes similar to box 10 herein shown supported on the bracket 11 and is adapted to have an adjustment thereon to and from the iron window sill 12.

13 is a bracket secured to the'boX, and 14 is a similar bracket secured to the operating rod by means of the Ushaped clip 15.

16 is a bracket pivotally supported tothe bracket 13, and 17 is a bracket pivotally supported to the bracket 14. The operating lever 18 is pivotally supported at one end on the pin 19 projecting from the bracket 17, and at the opposite end on pin 2O located on one end of the locking lever 21 pivotally specification orretters Patent.

serial no. 12,729.

j fulcrum lever 24 is pivotally supported at one end to the pin 25 projecting from the operating lever 18, and at'its opposite end on the pin 26,' which pinv is adapted to have a longitudinal movement in the slot 27 for the purpose presently to be described.

28 is a stationary locking pin projecting from the window sill adapted to be engaged by the locking lever when the window is closed.

To open the window, the rod 9 is longitudinally actuated in the direction of arrow a, Fig. 2. The bracket 14, as before mentioned, being secured to the rod, will move therewith and force the operating lever 18 in the direction of arrow Z), and also cause a temporary idle movement of the ulcrum lever 24 in the direction of arrow c. This idle movement of lever 24, while its pin 26 is trc veling in the slot 27, is absolutely necessary to allow the locking lever 21 to disengage itself from the pin 28, and when this is accomplished, the pin 26 will have brought up against the end of said slot to form a fulcrum point for the lever 18, which will exert an outward push against the window just as soon as that part of the arm of the locking lever, to which the lever 18 is pivoted, is forced against the bar 23 of the movable window frame as shown in Figs. 3 and 4. As the levers 18 and 24 swing outward, the brackets 16 and 17 will turn on their pivotal supports to compensate for the diii'erent angles these levers will assume during the outward movement of the window. The closing of the window by a reverse movement of the operating rod 9 f placed at such suitable intervals as will give the best result; or a long line of window units with the operating device connected to each unit ,could be arranged if desired. While I show the locking device associated with a window swinging from the top, it is applicable to windows openingin any di rection.

Having tlius described invention,:what` I claim is A Window operating device comprising a pivoted locking lever carried by the Window,

"5 means adapted to be engaged bythe lever to 10 carried by the operating rod, a fulcrum lever pivoted at one end to the operating lever and at its other end to a movable pivot adapted to have a limited travel in a support pivoted to. a stationary part of the device While the operating lever is unlocking the i5 locking lever.

In testimony whereof I afHX my signature Y in presence of two Witnesses.
